Hong Kong Building Age Lookup Map

Want to know how old a building is before viewing a flat? "HK Utility Map" uses the Buildings Department’s building information and age records to show completion years for nearby buildings.

Why Building Age Matters

A building’s completion year affects maximum mortgage tenor, whether the Mandatory Building/Window Inspection Scheme (MBIS/MWIS) applies, and expected future maintenance costs. This is a reference tool only — for legal building records, consult the Buildings Department directly.
